VALVE.

Application filed April 2, 1926. Serial No. 99,389.

This invention relates to a valve, and is more particularly intended tobe used for controlling the fiow of fuel gas in an incinerator. In theform of incinerators in which S this valve is intended to be used, thesame fuel gas when the pile of refuse in the incinerator is completelyconsumed.

It has been found that where a regulatmg gas valve was provided in anincinerator,

there was a tendency on the part of the op-l erator to turn the gasdown, and operate the incinerator with an insufficient supply of gasespecially when the operator was leaving the house lor a length of time.While a complete reduction oll the refuse was et'r'ected, this operationresulted in an incomplete combustion of the refuse and the consequentproduction ot obnoxious unconsumed gases and fumes which were carried tothe eXterior of the building and produced avdisagreeable odor around thesame.

The principal object of this invention therefore is to provide al valvewhich is either completely open or completely closed, and which whencompletely opened is locked in such position until tripped automaticallyor by hand.

Further objects are to provide such a valve which is simple andinexpensive in operation and not' liable to get out of order throughconstant use.

In the accompanying drawings:

Figure 1 is a top plan View of the valve.

Figure 2 is a vertical longitudinal sectional view of the same,

Figure 3 is a fragmentary view showing the means 'for limiting theupward movement ot the locking bar.

Figure 4 is a front end view of the valve.

Figure 5 is a side elevation of the same.

Similar' characters of reference indicate like parts in each -o theviews.

, The valve housing is composed of two sections 6 and 7 which are joinedby a screw connection 8. The rear section 7 is provided with an interiorwall 9 forming an outlet chamber 10 in the rear ofthis section, and thiswall is provided with an opening 11 around which is formed a forwardly'facing conical valve seat 12. An outlet 13 is provided in rear of thewall 9 and is a'dapted to be attached to the pipe (not shown) lead ingtothe gas burner, and a laterally projectlng inlet 14 is provided in'li-ont of the wall 9 and is adapted to be secured to the gas manifold(not shown)` in any suitable manner.

A longitudinally movable plunger l5 is slidably` mounted in the frontend of the front section and at its rear end is provided with a conicalhead 16 adapted to engage the` conical valve seat and cut off the'low ofgas through the valve. The plunger is normally held in its. rearward orclosed position by la return spring 17 surrounding the inner end of theplunger vand interposed between the housing and the head 16.

The plunger is drawn forwardlyby an upright operating lever 1S which ispivotally secured at its center to the outer-end of the plunger and atits lower end is pivotally secured to a forwardly projecting lug 19formed integrally7 with theiront section 6 of the valve housing. Theupper end of the operating lever is suitably shaped to provide aconvenient handle for the operation of the valve and the lower end 2O isin the form of a blade which is received in longitudinal slots 21 and2:2 provided in the outer end of the plunger and the lug 19,respectively, and held therein by transverse pivot pins 23 and Q4. Theblade 2O of the operating lever is formed to permit the plunger to bedrawn outwardly kand its lower rear edge 25 is curved and adapted toengage and bear against the bottom or rear end 26 of the slot- 22 whenthe lever is moved forwardly thereby relieving and preventing wear onthe pivot pin Q4 when the valvey is being opened. yThe movement of thepivot pins 23A and 24 toward and from each other as the valve is closedand opened is permitted by providing a curved opening Q7 in the lowerend ot the operating lever which is penetrated b v the pivot pin 24:yand thereby provides a sliding connection at this point. The opening issomewhat wider than the pivot pin therebyk permitting the rear edge ofthe blade 2O to freely engage the bottom 26 of the slot 22 and is curvedto conform to the movement of the lower end of the blade relative to thepin 2li, thereby insuring free movement of the operating lever.

In order to lock the plunger when the same is drawn to its fully openedposition, and hold the valve open until released automatically ormanually, the plunger is provided wi th a recess 28 on its upper sidewhich is arranged outside of the valve housing when the valve is fullyopened and is adapted to receive the lower edge of the transverselocking bar 29.

The locking bar rests against the forwardly facing flat side 3() of t-hevalve housing. and is pivotally secured at 31 to a lateral extension 3Qso as to be capable of swinging upwardly and downwardly. rlhe free orouter end of the locking bar extends across the upper side of theplunger, and in the closed or in ard position of the plunger rests onthe upper side thereof. lVhen the plunger' is drawn outwardly to itsfully opened position, the locking bar drops by gravity into the recess`28 provided on the upper side of the plunger and prevents the valve fromclosing until the locking bar is tripped. In order to prevent undue wearof the plunger at the front corner of the recess 28, a hardened pin 36is set into the plunger at this point as shown in Figs. 1 and 2.

To prevent the locking bar 2f) from being raised further than isnecessary to free the plunger, the saine is pivoted between an L- shapedsupport 33 and the extension 32, and the under side of the locking baris recessed to form a catch or stop 34; which is adapted to en acorresponding stop face 35 on the support when the bar is aised andthereby limit the upward movement of the bar.

As a whole this valve is extremely simple and durable in constructionand is not liable to get out of order or wear unduly through constantuse; it operates reliably7 to perform the function set forth and is notliable to become accidentally tripped or released.

I claim as my invention:

l. In a valve, a valve mechanism having a longitudinally movableoperating plunger, said plunger having a recess on its upper side, alocking bar pivotally mounted to one side of said plunger and extendingtransversely across the upper side thereof, the longitudinal edge ofsaid locking bar beinr adapted to drop into engagement with said recessand hold said plunger in one position, and the outer end of .saidlocking har being formed to provide a handle whereby the locking halifted to release said plunger.

A valve comlirising a valve housing having a valve seat and an inlet andoutlet arranged on opposite sides ot said seat, a longitudinally movable)pilunger mounted on ,said valve housing and adapted lo engage. saidseat, a spring tending to hold .said plunger in engagement with saidseat, .said plunger projectng outwardlyv from said casing and beingprovided on itsl upper side with a recess, and said casing beingprovided with an exterior transverse flat face adjacent said plunger,and a llat locking bar pivotally mounted on said face of the 'using toone side of said plunger and extending across the upper side thereof,.said locking bar being adapted to drop into said recess and hold saidplunger in an outward position. and the outer end ol` said locking barbeing formed to provide a handle whereby the locking bar lifted to relase said plunger.

il. A valve comprisingr a valve housing. a valve mechanism arranged insaid housing and having a longitudinally movable actuating plungerprojecting outwardly therefrom; means tending to hold said plunger inits inward position, means for drawingr said plunger outwardl)vcomprising an operating lever pivoted centrally to the outer end of saidplunger, and a lug projecting forwardly from the lower end of saidhousing, the lower end of said lever heilig slidnglv secured to saidlug. and means for locking said plunger in its outward positioncomprising a locking bar pivoted to said housing to one side of saidplunger and extending across the upper side of said plunger, saidplunger being provided with a recess on its upper side into which saidlocking bar is adapted to drop when said plunger is in its outward pirsition.

In testimony whereof l hereby allix my signature.
